      Well said @Kevin72836 and @feelincrispy7053 - - and let's not forget the equally tragic loss of Jesse Combes.
      Grant was an amazingly natural 'science communicator', both he and Jesse brought so much to Mythbusters in their own unique way.
      Such a terrible, immensely sad loss. And one really feels for their families.
      With the whole team it felt as though they were all as invested in the experiments as the viewers were, as though they were all as passionate about the show, and as interested in the outcomes as we were - and I don't think you can fake that enthusiasm just for the camera.
      Furthermore, the interaction between the teams, during and between builds, and experiments etc, was all the more entertaining because it wasn't scripted, there was genuine laughter.
      Rest now Grant and Jesse: you are so sorely missed, you will not be forgotten. And thank you both for your dedication, skill and enthusiasm. Along with the entire Mythbusters team you made Science accessible and S.T.E.A.M. cool.
      Thank you all.

    My uneducated best guess about "thermite + ice = explosion" thing is that a portion of the water ends up skipping the liquid state?
    1) We start with ice with thermite on top, unlit
    2) As we light it, thermite melts a portion of the ice (top layer) to water
    3) Water (that's quickly becoming steam) and burning thermite mixture gushes over the sides & encapsulates the ice
    4) Ice melts from all but 1 side now, all that water again quickly turning to steam, increasing pressure as heat is still increasing
    5) We reach a breaking point where theres is a core of ice inside a hot & pressurized capsule of steam and thermite
    6) Physics.exe goes "hmm this aint right" and and the ice *_instantly_* goes to steam, roughly 1600x the size
    7) Profit

    I think the SKS myth needed music to be a true test. But I also think it may have been a poorly treated rifle in a pile of rifles left loaded with safeties off. Pile shifts and some other item, maybe a bolt or a sight, glanced off of a trigger n set off 1 rifle. Which set off another and so on.

    15:37 - Based on what I learnt in Physics and Chemistry in University, I have 3 Hypothesis for what happens with Thermite and Water Ice. 1) Like Jamie said, at 4,000°C, a lot of the water in the ice will decompose into Hydrogen and Oxygen, and because of the enormous heat present will recombine.
    2) Water Ice contains a lot of trapped air bubbles. With the radiative heat from Thermite shining so much infrared radiation through the relatively clear ice, all these millions of tiny air pockets turn into superheated gas in an instant, with explosive result.
    3) At 4,000°C the Water in Water Ice sublimates instantly, that is it turns from the State of being a Solid, skips the State of being Liquid, but jumps straight into becoming a Gas, a superheated, Dry Steam.
    I believe that all these three hypothesis of mine are present concomitantly, and each one of them yields an explosive result on it's own. When they said what they were going to do, I knew the result would be explosive.
    And let's not forget, that with 1), 2) AND 3) happening at the same time, for a split second, the Thermite will be spread into an AIR-FUEL MIXTURE! Air-Fuel Bombs are some of the most powerful bombs on the planet. However, this Air-Fuel is probably secondary to the first three reactions.

      @Yourmomma568 Місяць тому

      If simple rapid gas expansion was to blame, then presumably it would be even more explosive with dy ice, which takes much less energy to go from solid to gas... But it doesn't. People always forget that aluminum is explosive, and it explodes with just plain water as well. It has nothing to do with rapidly expanding water vapor. The science is not well understood. Only in the last 5 years was the first paper published that explained the detonation of alkali metals with water. You could hypothesize that it's the same type of reaction. Aluminum, when molten, forces it's oxide layer to the surface. Thermite can get hot enough to decompose this oxide layer completely. Pure aluminum (no oxide) and water react like this, Al2+3H2O->Al2O3+3H2. This reaction occurs very rapidly, with the same E∆/t as dynamite. Just google the aftermath of aluminum foundry explosions. It's like the MOAB going off. Why people have a hard time replicating it with molten aluminum and water is because they typically pour the aluminum from a crucible into water. They are very lucky. Aluminum will very quickly develop an oxide layer as it is pouring, which limits the reaction severely. If you poured water into a large crucible, there's a good chance it will go boom. Probably with enough force to kill you and shater your neighbor's windows. Why thermite works eith ice but not water, is because thermite burns hot enough to decompose the oxide layer, but usually not while subjected to evaporative cooling. Of course, water dumped on thermite can cause some small partial explosions, and will shower sparks everywhere, but with ice, the water, and exposed thermite can come in contact without causing rapid cooling of the thermite, and lacks the plastic deformation characteristics that inhibit deformation of the oxide scale. Tldr, aluminum is explosive and reacts with water. The fact that it only works with ice is just a coincidence of physics.

      They did 2 revives and both failed
      - First one was like half a year after the original show stopped, some sort of "hunt for the new Mythbusters" that featured a bunch of youtubers competing to become the new Mythbusters (check out "safety third" podcast about it featuring a few of them, apparently that was all kinds of weird & rigged)
      - Second one was fairly recent, some kind of "mythbusters for kids" with Adam Savage & Tory Belleci
      Neither of these were really aired internationally, only a few countries got to see them, but it's probably for the best as both honestly did the original a disservice, you're not missing out if you haven't seen these.
      There was also some show from Kari & Tory (i wanna say for 'Spike' channel?) that had a similar vibe but didn't have any official relation to Mythbusters & only lasted like 2 episodes, its possible they got shut down by Discovery.
      The fact that they've sold the rights now (this channel actually owns Mythbusters) means there probably won't be a third attempt.

  • @TheWolvesCurse
    @TheWolvesCurse 9 днів тому

    my guess for the thermite explosion is the sudden thermal expansion of the water causing the explosion.
    the same thing would've happened at a vastly larger scale, if the 3 technicians wouldn't have crawled in the lower levels of the Chornobyll powerplant, to open the valves of the feedwater tanks, to drain them. if the molten core at it's peak temperatures would've reached those tanks holding several ten thousands of liters of water, the sudden thermal expansion would've cause an explosion of a several kiloton TNT equivalent, and spread radioactive material much further than it already has been spread by the first explosion.
    to prevent the molten core from burning further down through soil into ground water, some coal miners have dug under the plant to install a heat exchanger.
    the temps of the molten core are somewhat comparable to thermite, it just burns longer and more steadily.

    I think they may be looking for more complicated explanations than needed. Water turning in to steam expands to around one thousand times it's volume; So IF the thermite actually burns hot enough to not just melt but even turn it in to steam fast enough, it will be an explosion.. (or proper terminology would probably rather be "uncontrolled decompression") inside of the ice and the ice will itself around the the extreme pressure.. (Like blowing a fire-cracker in your hand.. Even a small one can ruin your hand IF you clench it around the cracker, but if it lays flat yon your open palm you may not even really get a scorch).

      @@stasi0238 .. Not sure what you mean; The problem with trying to get water to "explode" by heating it is that.. WHEN it turns hot enough to turn to steam it DOES turn to steam and.. leaves.. AND water turning in to steam takes a lot of energy, which is why pouring water on fire is such a good way to put out fires, it cools down the fire.. But water CAN "explode". You heard of boilers exploding?.. What you need to do is to keep the water around for long enough time so it gets to build up pressure, so instea of just fractions of a gram turning in to steam a LOT of it turns in to steam at the same time.. That is where the ice would come in; It becomes the solid encasement that keeps the water in place so enough of it will decompress at the same time.
      It's like a fire-cracker. A small fire-cracker in the palm of your hand won't even burn you.. but close your hand and you will lose your fingers. It's about whether the expanding matter has some place to go or if it has to "force" it's way.

      @@rogerlundstrom6926 I'm not stupid lol. I'm talking about experiment in question. Thermite on ice violently explodes, but thermite that goes into water doesn't. If you are talking that pressure builds up in ice better than in water, remember that thermite is the source of heat so the nearest ice particles to thermite are turning to steam then further water and further lays ice, so there is no way to pressurize the steam. My opinion is that either aluminium or iron in the reaction is hot enough that it reacts with water as in X(metal) + H2O = oxide/hydroxide + H2. We can see this reaction working at room temperature with sodium or potassium and we can see similar explosion. The question about water not working makes sense then because hot metal can't react well with water since it creates a steam barrier better itself and liquid metal, and it makes sense that ice can't move like the water to allow liquid metal not to touch it.

Just to say; I have NEITHER done experiments, NOR done the maths to "know" whether this is true, I am ONLY relying on occhams razor: IF you already can explain things with what you already know, then stop trying to look for strange other explanations.
      So. .The thing is.. Water expands when it turns in to steam..thousand-fold.. this decompressin is EXTREME and creates a LOT of power.
      BUT... If you (f.ex.) boil water.. then.. it doesn't explode.. the REASON it doesn't explode is because one single water-molecule turning in to steam.. means.. it turns in to steam and DOES require a bit more space.. However, that ONE molecule has expanded a LOT! but it CAN traverse and expand, and so on.. QUITE a bit.. BUT.. it's expansion ALSO will cool down all the water that surrounds it.. at the time it is endothermic.. it sucks out the energy of the water around it so that water is COOLED.. (as I mentioned about why water IS the way to fight fires).. It SUCKS energy.. it COOLS it's surrounding.
      But more importantly: WHEN talking about a pot boiling.. the actual.. water that turn into gaseous form.. it.. will create bubbles in the pot.. and.. rise.. and.. cool down everything else.. and.. then.. float to the top.. and.. just go out.. it may have expanded a LOT but it is just a FRACTION of the actual amount of water in the pot.. and.. it cools down the water.. this is why a boiling pot IS 100 degrees centigrade and will never never ever PASS it.. you need to put it in a closed system for you to be able to heat water BEYOND 100 degrees centigrade.. if the water that passes this temperature is able to leave then.. it will leave.. and not affect the actual full system too much.... beyond actually COOLING the water.
      HOWEVER.. It's a matter of "speed".. and.. Even IF ice could melt.. it's about the speed of light.. Energy traversing can't go faster than the speed of light.. .so if you FLASH!!! heat ice to the point BEYOND melting.. then.. that part of the equation means it takes 1000 times more space than it used to take.. BUT if the actual "Ice" keeps it in.. then.. INSTEAD of water reaching the actual boiling temperature CAN'T easily disperse and just.. go into the atmosphere. then.. the pressure will build.
      the consequence of pressure building IS.. an uncontrolled decompression.. (Which is VERY similar to an.. Explosion.. MOST people wouldn't know the difference in the first place).. .. So.. SERIOUSLY.. IF you have an ice-block, and water SUDDENLY turns in to steam in the middle of all that ice.. it WILL create an explosion like event. .but.. if it instead was happening in the mid of WATER then it.. would just turn in to it's gaseous form and be FREE to escape the medium within which it was "trapped".*
      and I am not even trying to say that "I am right".. I am JUST saying that the most OBVIOUS solution to this conundrum doesn't even seem to be what people are pondering at all. they are IGNORING the thing that is in clear sight and trying to invent new solutions.. So.. I may ABSOLUTELY be wrong.. I don't question that.. I only say that.. you CAN solve this without resorting to zebras.. and.. you should look for ways to check whether the things that we ALREADY know of (such as exploding boilers) ISN'T the reason... before trying to claim it is "unknown" behaviour.

    The most likely way for the SKS myth to be true is if the guns were sitting against the cone of the speaker. A big bass note will jolt the entire gun with enough force for the pin to set off the primer. It would be like dropping the gun. Subwoofers are often in the trunk and large, illegal rifles are also often kept in the trunk and out of sight. Gangsters probably don't have cases that secure the gun, but have them just laying there.
    The issue with the SKS myth as tested s that a firing pin that large isn't going to vibrate with enough force, if at all. You need intermittent heavy bass notes, which shake the entire rifle once. Inertia is probably the culprit if the myth is real. The gun moves from the vibration, the firing pin is floating and isn't moving with the gun. As soon as the pin hits the end stop, it gets shot in that direction, hitting the primer, firing the gun

      I was thinking the rifles could've also been stored vertically, fallen from vibrations and fired. Far more likely with music than pure tones, it was an odd choice not to use music.

      ​@@Cheynanigans__ Tones can easily be controlled, so they chose that.
      Given the design issue with the bolt, the rifle needs to be moved forwards and backwards really quickly and violently. Falling over wouldn't really do that.

    Funny how I always thought this was a legitimate science show when I was younger, and now seeing it again grown wiser noticing how much more show than actual science it is. Since when are bird bones as dense as human bones? And I'm sure they knew in advance that turning ice into steam instantly causes an explosion without having to test it as a myth haha
    But still a good way to get kids interested in science though.

    many weapons are springless. an a R1 5 style r ifle is another example.
    without enough momentum the fire pin can't deflagrate the primer.
    shall be no deflagration unless the sks am-mo uses some bad pistol primer, or the vibration has more energy than a hammer hiting the primer

    Its too bad they were using pristine guns, although understandable for safety reasons, but I've held guns that went off from the slightest movement just because the trigger mechanisms were so worn out they'd go off from simply tilting the gun downwards, and a good enough subwoofer with the right song and no safety would definitely set them off

    Perhaps the rapidly expanding water creates room in the thermite storage, providing more room for oxygen and thus more combustion, creating even more room, and so on and so on. In mere milliseconds that is. Kind of the same idea when you have a flame in a hot pan with oil or fat, trying to extinguish it with water is a bad plan for similar reasons.
    The decomposion theory is dismissed. Water never decomposes through heat (at least not in earthly conditions), but rather through electrical current

  • @DIREWOLFx75
    @DIREWOLFx75 Місяць тому +4

    The reason why you never ever try to extinguish fire with hot water... Or in other words, if there's a fire in your cooking pot or pan, do NOT put water on it.
    The water can vaporise instantly and generates a steam/fire explosion.
    "it's a mystery"
    REALLY? The heat causes the ice to become steam, the steam spreads the thermite out causing it to burn faster, as it's basically becoming a dust explosion, which accelerates the heat production even more rapidly and making a massive feedback loop.
    Essentially, you're making a STEAM explosion combined with turning burning thermite into a dust explosion.
    It's POSSIBLE there's also some level of turning part of the steam into oxygen and hydrogen, adding to the explosion, but that's unlikely to be a majority component of the effect.
    "dodgy rifles"
    That's like calling the M-16 dodgy.

    I always thought the Thermite vs Ice was a meeting of equal and opposite forces. The thermite can't melt the ice fast enough, and the ice can't extinguish the thermite. Something in that equation has to give, and so eventually the whole thing goes boom. I'm certainly no expert, but that's my guess.

    i noticed with all lot of your tests , you don't seem to follow the same environment as the myth, you didn't include a bass drum thump that takes advantage of the peak power of a sub woofer. Peak power is much higher than rms power and the thump of a bass drum moves a lot of air. the repetitive nature of music is not in your test .
    in my opinion , you proved nothing

  • @jeschinstad

    I think what happens is leidenfrost + thermolysis; the thermite burns so hot that the ice turns into steam, insulating it from the ice while the burning thermite covers it from the top. The steam can then be heated up to the 3000c/5400f that is required to split water into hydrogen and oxygen. HHO burns extremely hot, so now you're adding even more extreme heat that can't escape, creating more HHO, which creates more HHO. This is a runaway reaction, also known as an explosion. It would've been interesting if they could've tried this the other way, putting the ice on top of the thermite.
